How to idetify the error source when "The program has unexpectedly finished." ?

Anonymous_Banned275

This has probably been asked before.
The attached app output does not tell much. Actually the "time stamp " seems pretty superficial "bells and whistles".
Most of the output is due to extensive usage of "debug".

I have a nasty bug in my system and it periodically adds stuff at random, so I really cannot go to "lass changes made ".
( I just added tool tip in QDesiger and copy of it ended up in source code ! Found it!)

I am simply "stepping thru " break points, but that is pretty tedious.

Can compiler / linker be optioned to provide more info , at least getting into a ball-park of the error ?

Hi

-Can compiler / linker be optioned to provide more info , at least getting into a ball-park of the error ?

The call stack panel in Creator shows all the last stuff it was doing. That often gives a hint
on what it did before the crash.

Yes its boring. but sometimes needed to find the exact spot for the crash.
